Book Synopsis Just Six Numbers by : Martin Rees

Download or read book Just Six Numbers written by Martin Rees. This book was released on 2008-08-04. Available in PDF, EPUB and Kindle. Book excerpt: How did a single "genesis event" create billions of galaxies, black holes, stars and planets? How did atoms assemble -- here on earth, and perhaps on other worlds -- into living beings intricate enough to ponder their origins? What fundamental laws govern our universe?This book describes new discoveries and offers remarkable insights into these fundamental questions. There are deep connections between stars and atoms, between the cosmos and the microworld. Just six numbers, imprinted in the "big bang," determine the essential features of our entire physical world. Moreover, cosmic evolution is astonishingly sensitive to the values of these numbers. If any one of them were "untuned," there could be no stars and no life. This realization offers a radically new perspective on our universe, our place in it, and the nature of physical laws.

Book Synopsis Just Six Numbers by : Martin Rees

Download or read book Just Six Numbers written by Martin Rees. This book was released on 2014-03-20. Available in PDF, EPUB and Kindle. Book excerpt: Astronomer Royal Martin Rees shows how the behaviour and origins of the universe can be explained by just six numbers. How did a single genesis event create billions of galaxies, black holes, stars and planets? How did atoms assemble - here on Earth, and perhaps on other worlds - into living beings intricate enough to ponder their origins? This book describes the recent avalanche of discoveries about the universe's fundamental laws, and the deep connections that exist between stars and atoms - the cosmos and the microscopic world. Just six numbers, imprinted in the big bang, determine the essence of our world, and this book devotes one chapter to explaining each.

Book Synopsis The Nine Numbers of the Cosmos by : Michael Rowan-Robinson

Download or read book The Nine Numbers of the Cosmos written by Michael Rowan-Robinson. This book was released on 2001. Available in PDF, EPUB and Kindle. Book excerpt: How old is the universe? How far away are the galaxies and how fast are they travelling away from us? What is dark matter and why do astronomers think it pervades the universe? How heavy is the vacuum? How do galaxies form?Michael Rowan-Robinson answers these and many more questions in a highly original and intriguing way. He encapsulates our current knowledge (both what we do and don't know) of the origin and the nature of the universe into nine numbers. These cosmic numbers appear to be independent characteristics of our universe and include its age, the Hubble constant (a measure of its rat.

Book Synopsis The Little Book of Cosmology by : Lyman Page

Download or read book The Little Book of Cosmology written by Lyman Page. This book was released on 2020-04-07. Available in PDF, EPUB and Kindle. Book excerpt: The cutting-edge science that is taking the measure of the universe The Little Book of Cosmology provides a breathtaking look at our universe on the grandest scales imaginable. Written by one of the world's leading experimental cosmologists, this short but deeply insightful book describes what scientists are revealing through precise measurements of the faint thermal afterglow of the Big Bang—known as the cosmic microwave background, or CMB—and how their findings are transforming our view of the cosmos. Blending the latest findings in cosmology with essential concepts from physics, Lyman Page first helps readers to grasp the sheer enormity of the universe, explaining how to understand the history of its formation and evolution in space and time. Then he sheds light on how spatial variations in the CMB formed, how they reveal the age, size, and geometry of the universe, and how they offer a blueprint for the formation of cosmic structure. Not only does Page explain current observations and measurements, he describes how they can be woven together into a unified picture to form the Standard Model of Cosmology. Yet much remains unknown, and this incisive book also describes the search for ever deeper knowledge at the field's frontiers—from quests to understand the nature of neutrinos and dark energy to investigations into the physics of the very early universe.

Book Synopsis Gravity's Fatal Attraction by : Mitchell Begelman

Download or read book Gravity's Fatal Attraction written by Mitchell Begelman. This book was released on 2009-12-21. Available in PDF, EPUB and Kindle. Book excerpt: Richly illustrated with the images from observatories on the ground and in space, and computer simulations, this book shows how black holes were discovered, and discusses our current understanding of their role in cosmic evolution. This second edition covers new discoveries made in the past decade, including definitive proof of a black hole at the center of the Milky Way, evidence that the expansion of the Universe is accelerating, and the new appreciation of the connection between black holes and galaxy formation. There are entirely new chapters on gamma-ray bursts and cosmic feedback. Begelman and Rees blend theoretical arguments with observational results to demonstrate how both approaches contributed to this subject. Clear illustrations and photographs reveal the strange and amazing workings of our universe. The engaging style makes this book suitable for introductory undergraduate courses, amateur astronomers, and all readers interested in astronomy and physics.
